Assessment

Why?

Strongest counted support: The study reports stronger corridor concentration through 2500 BCE, followed by weakened association and a shift toward intermediate-accessibility settings. weight 1.800000 evidence

Suppressed as dependent: The quoted passage directly states the earlier accessibility association and its later weakening with a shift toward intermediate-accessibility settings.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

• An independent regional study found persistent settlement clustering and later spatial reorganization, broadly consistent with the claim's clustering component but not a direct test of the national accessibility gradient.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
